Title: Methods for the desalting of biologic samples to eliminate disturbances in isoelectric focusing
Inventor: LIAO JIA-LI
IPC: G01N27/447
Filed: 1995-06-06
Abstract: The present invention provides new methods for desalting samples of ionic polymers or weak electrolytes, preferably ampholytes (e g., peptides, proteins and glycoconjugates) or, compounds which can be transformed into these substances by complex formation. The methods of the present invention are based on the fact that salts can be removed from a sample by electrophoretically replacing the salts with ampholytes present in the ampholytic media of the anolyte and the catholyte or, with displacing cations and anions that have been introduced into the anolyte and catholyte, respectively, and which have mobilities less than the mobilities of the cations and anions to be removed from the sample. Although applicable to both small-volume and large-volume samples, the methods are particularly well suited for small-volume samples. Moreover, when applied to capillary electrophoresis, the methods described herein permit desalting of a sample in the same capillary tube as is used for the electrophoretic analysis. Alternatively, however, the sample can be withdrawn from the capillary tube following desalting and processed by techniques other than high-performance capillary electrophoresis (HPCE). Regardless of which method is used, the desalting methods of the present invention are rapid, highly reproducible, and they give a high recovery of sample compared to dialysis.

Abstract: A liquid absorbent material used in a pouch for a stoma comprising a laminate sheet having surface layers formed of water soluble or dispersible paper and an intermediate layer formed of a web comprising a mixture of a fibrous cellulosic absorbent resin and a powdery synthetic polymeric absorbent resin, wherein a plurality of linear recesses are arranged at such a pitch that the laminate sheet is easily tearable into each of fine sticks that can be inserted, for example, from a urine discharging tube into a stoma pouch for a urinary tract stoma.  Liquid excrements flowing out of the stoma into the bag of the pouch can be rapidly solidified into jelly by the liquid absorbent material, thereby reliably preventing liquid excrements or bad smells thereof from leaking through the attaching port of the pouch or the like and preventing liquid excrement from deposition to the adhesives used for securing the pouch to the abdominal wall which would lead to deterioration of tackiness of the adhesives, to enable repeating use of the stoma pouch.

Title: System and method for noninvasive detection of arterial stenosis
Inventor: KOSTIS JOHN
IPC: G06F17/00
Filed: 1996-08-15
Abstract: This invention is a system and method for non-invasive detecting of coronary artery disease. The system and method utilize a vasodilator drug to increase the signal to noise ratio of an acoustic signal that represents diastolic heart sounds of a patient. A wavelet transform is performed on the acoustic signal to provide parameters for a feature vector. Scaled clinical examination parameters, such as a patient's sex, age, body weight, smoking condition, blood pressure and family history are also included in the feature vector. The feature vector is used as an input pattern to neural networks (208). The output of the neural networks (208) represents a diagnosis of coronary stenosis in a patient.
Patent CA-2203200-A1 (CA)
Inventor: KLEIN EDWARD P
IPC: D21H23/42
Filed: 1997-04-21
Abstract: In the patented Menser apparatus for saturating a substrate with a liquid saturant, or resin, by conveying the substrate through a resin chamber, the invention improvement is disclosed whereby the apparatus is modified by the installation within the chamber of a separation means, such as a bar, to redefine the path of the substrate through the chamber filled with liquid saturant.  Rather than having the substrate pass through the chamber following the path defined by the periphery of the lower portion of the circumferential surface of a mandrel and only being directly contacted by the liquid saturant on one side of the substrate, the redefined path creates a separation of the substrate from said periphery thereby permitting the liquid saturant to contact the substrate on opposing sides to achieve optimum saturation of the substrate by the liquid saturant in volume and uniformity.  Inasmuch as the geometric principles which cause an increase in pressure within the chamber as the substrate travels from its entrance into the chamber to its exit, the benefits in saturation provided by such pressure increase are enhanced by the invention as, by the invention modification, they are received on opposing surfaces of the substrate.

Abstract: A wireless communication system having a terminal unit (12) operates in a reduced noise state during receipt of a wireless transmission from a control unit (14). The terminal unit (12) includes terminal circuitry (16), a radio (18) and noise management circuitry (20). The noise management circuitry (20) partially or fully disables operation of the terminal circuitry (16) during a receipt by the radio (18). Noise management circuitry (20) may disable a terminal processor (302), disable interrupts, buffer interrupts and otherwise modify operation of the terminal circuitry (16) to reduce generated radio noise that would otherwise interfere with receipt of data by the radio (18). The wireless communication system includes noise management circuitry located in a control unit (206) that operates in conjunction with noise management circuitry in a first terminal unit (202) and a second terminal unit (204) to schedule transmissions from the control unit (206). These scheduled transmissions allow the terminal units (202) to perform required processing functions outside of the reduced noise period.

Title: Conversion system with electronic controller for utilization of gaseous fuels in spark ignition engines
Inventor: KLOPP GERHARD O
IPC: F02D19/06
Filed: 1997-08-25
Abstract: A  conversion  system  for  converting  a  spark ignition engine to operate on gaseous  fuel is disclosed. The  conversion  system  includes  an  electronic  controller which  operates  on  several  novel  principles  to  provide superior performance/responsiveness  and to  reduce exhaust emissions.  The controller in accordance with the invention assumes  complete  control  of  spark  ignition  timing  when gaseous fuel mode is enabled and generates independent spark ignition  signals  tailored  to  the  gaseous  fuel.    The controller  also  generates  an  independent  pulse  width modulated gaseous fuel injection signal that controls a high performance  electronic  solenoid  injector valve to  supply gaseous fuel to the engine.  Variable injector speed is used to compensate for the dynamic range of the engine.  A novel dual array block learn scheme is used to provide efficient fuel control in engines equipped with closed-loop monitoring systems and exhaust gas recirculation.   A gasoline power boost mode  is  also  provided to  enable  extra power when maximum engine torque is commanded.   The advantage is an efficient  fuelling  system  which  provides  all  of  the advantages  of  gaseous  fuels  while  preserving  the  power capabilities  of  liquid  fuels,   and  minimizing  exhaust emissions.
